Select MenuItems dont respect `shouldDismissPopover={false}` when selected with `Enter`

[bradymadden97]

Environment

• Package version(s):
  "@blueprintjs/core": "^6.12.0",
  "@blueprintjs/select": "^6.1.9",
• Operating System: macOS Version 26.3
• Browser name and version: Island 1.85.25 Chromium: 145.0.7632.117 (Official Build) (arm64)

Code Sandbox

Link to a minimal repro: https://codesandbox.io/p/devbox/exciting-payne-swcdjy

Steps to reproduce

1. Create a <Select /> component that's queryable and has a couple menu items with shouldDismissPopover={false}
2. Click them - expect popover to not close
3. Move selection using arrow keys up and down - works fine
4. Hit enter - expect popover to not close, but it closes

Actual behavior

• Popover closes when shouldDismissPopover is false and you press Enter

Expected behavior

• It stays open and respects the prop

Possible solution

We check the event.target here in order to see if the menu/menu item has the popover dismissal class on it. When pressing enter, the event.target is actually the input box, not the menu item, so the rest of the code in this block doesn't search correctly. Not sure exactly what the right traversal is to fix this, but this is clearly where the bug is.

const target = event?.target as HTMLElement;
